Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"model learning method algorithm" » "model learning mom algorithm", "model learning methods algorithm", "model graining methods algorithm", "model learning emotion algorithm", "mobile learning method algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("model learning method algorithm") or ("modified multiobjective optimizer algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("model learning method algorithm") OR ("modified multiobjective optimizer algorithms"))*.
• Removing quotes may allow a broader search: (( model learning method algorithm ) or ( modified multiobjective optimizer algorithms ))*.
